The findutils package consists of three programs.
"find" is a program which searches a directory
tree to find a file or group of files. It walks
the directory tree and reports all occurrences of
a file matching the user's specifications.
"locate" scans one or more databases of filenames
and displays any matches. "xargs" builds and
executes command lines by gathering together
arguments it reads on the standard input. Most
often, these arguments are lists of file names
generated by "find".
